Q:What diameter sonotube should I use with this product?
by|Oct 23, 2023
1 Answer
Answer This Question

A:  ​Hi Craig, this is Colin from Simpson Strong-Tie. The PB66Z requires 2" of sidecover, so you'll need at min a 12" diameter sonotube. The concrete requirements would be determined by a design professional. If you need more information or have additional questions, please contact the Simpson Strong-Tie Customer Service team at 800-999-5099. Thank you.

    Q:Can this be used to support fence posts?
    by|Dec 20, 2022
    1 Answer
    Answer This Question

    A:  ​Hi Carter, this is Colin from Simpson Strong-Tie. The PB does not provide adequate resistance to prevent members from rotating about the base and therefor are not recommended for non top supported installations such as fences. Are only post base that can prevent rotation at the base is our MPBZ (Moment Post Base). See our website at www.strongtie.com for more details. Type in keyword MPBZ in the search box. Or If you need more information or have additional questions, please contact the Simpson Strong-Tie Customer Service team at 800-999-5099. Thank you.

          Used this as a single mailbox support and it works well. Set it in quick-set concrete and installed the mailbox about an hour later. I used 1.5" exterior structural screws to attach it to the post and it works well.

          wobbly posts, but....
          these embed fine into concrete forms, but the post wasn't nearly as secure as I'd prefer. I ended up cutting 5 inches of sonotube and attaching a top my already mounted post base. I then filled that up with concrete to embed the entire connection into concrete. it doesn't wobble now, but a lot of extra effort. should have just embedded the post deep into the sonotube and skipped the hardware

            Do not use these brackets for a fence
            I recently had a concrete pad poured and the contractor set brackets for my 4x4 fence posts. To my absolute horror I am now stuck trying to figure out a way to brace these brackets for any lateral forces placed on the fence. My fence sways back and forth about as much as a drunk frat boy at his first college party. These brackets are total garbage and in my humble opinion should NEVER be used when installing above ground fence posts into concrete! Save yourself the heartache and make sure you are very specific with any contractor who bids out any concrete pad project on the type of brackets you want set. I am totally at a loss on how to brace my fence now without grinding off each bracket and replacing them with stronger ones utilizing red heads.

            Hello Hurricane, this is McKenzie with Simpson Strong-Tie. Except for our MPBZ, post bases do not provide adequate resistance to prevent members from rotating about the base and therefore are not recommended for non-top-supported installations (such as fences or unbraced carports).

              This is a good post base for 4x4s and 4x6s. You need to insert these when the concrete is wet. The other model with bolt should be used if not top load.

              It worked perfectly. This is very easy to use and is one of many that I have used in the past to secure the bottom end of a 10 foot light post in the ground without having to permanently cement the post in the ground.

              My old mailbox post was overdue for replacement. The 4x4 was reduced by rot below ground to about half it's original width and was full of termites to boot. So I set this post base in concrete and secured a new pressure treated 4x4 post to it after letting the concrete set for about 18 hours. I was a little disappointed at how flexible the resulting assembly was, much more than planting the post directly in the ground. So it remains to be seen how well it holds up in the years to come.

              I am trying these anchors for fences that have fallen. Drilled out rotted wood and cemented anchors on footer using existing concrete foundation. So far seems to work, fence a little wobbly, but still standing after 25 mph winds. I just purchase more for another section that has fallen. I would recommend this product.
